Best of the inbox: the pre-send list cleanse checklist

Best of the inbox: the pre-send list cleanse checklist
Before your next blast, this is the order of operations that catches spam traps and dead weight without nuking good contacts.

🧹 Hygiene
— Syntax + MX validation first — strip malformed and non-existent domains before paying for verification. Free filter, big savings.
— Suppress role accounts — info@, admin@, abuse@ are complaint magnets and frequent traps. Quarantine, don't mail.

🎯 Risk scoring
— Segment by last-engagement, not signup date — anyone silent 180+ days goes to a re-engagement sandbox, not the main send.
— Recycled-trap detection — old, suddenly-dead addresses are reactivated traps. Drop addresses that hard-bounced once, permanently.

🔁 Re-permission
— One last opt-in to the cold segment — a single 'still want this?' email beats slowly poisoning your domain.

Why these picks: they sequence cheap checks before expensive ones, and treat traps as a process, not a single tool.

Saved you ~2 hours and probably a blocklisting.
